济阳坳陷古生界逆断层地震解释方法研究
Seismic Interpretation of Paleozoic Reverse Faults in Jiyang Depression

济阳坳陷古生界潜山勘探潜力巨大，由于经历了印支、燕山、喜山等多期构造运动，构造特征十分复杂，现今仍残存许多逆断层。然而由于缺乏针对性的技术，逆断层地震解释存在较大的不确定性，为精细落实古生界构造带来了较大的困难。为此，文章在地质构造运动的背景下，通过地震反射特征分析，建立了逆断层地震识别依据，据此，通过低通滤波、视极性分析等方法对逆断层特征进行了较好的识别，结合地震解释技术对逆断层进行了描述，取得了较好的效果。
The Paleozoic buried hills are of huge exploration potential in Jiyang Depression. But the struc-tural characteristics are very complex characterized with many reverse faults which are the result of the Indosinian, Yanshan and Himalayan tectonic movements. Due to the lack of pertinent technology, there is great uncertainty in seismic interpretation of reverse faults, which brings great difficulties for defining Paleozoic structures more precisely. Therefore, under the background of geological tectonic movement, this paper establishes the basis for seismic identification of reverse faults by analyzing seismic reflection characteristics. Based this, the characteristics of reverse faults are well recognized by low-pass filtering and apparent polarity analysis. Combining with seismic interpretation technology, the reverse faults are described and preliminary results are obtained.
